NAME

Bio::Variation::AAChange - Sequence change class for polypeptides

SYNOPSIS

  $aamut = Bio::Variation::AAChange->new 
      ('-start'         => $start,
	'-end'           => $end,
	'-length'        => $len,
	'-proof'         => $proof,
	'-isMutation'    => 1,
	'-mut_number'    => $mut_number             
	);

  my $a1 = Bio::Variation::Allele->new;
  $a1->seq($ori) if $ori;
  $aamut->allele_ori($a1);
  my $a2 = Bio::Variation::Allele->new;
  $a2->seq($mut) if $mut;
  $aachange->add_Allele($a2);
  $aachange->allele_mut($a2);

  print  "\n"; 

  # add it to a SeqDiff container object
  $seqdiff->add_Variant($rnachange);

  # and create links to and from RNA level variant objects
  $aamut->RNAChange($rnachange);
  $rnachange->AAChange($rnachange);

DESCRIPTION

The instantiable class Bio::Variation::RNAChange describes basic sequence changes at polypeptide level. It uses methods defined in superclass Bio::Variation::VariantI.

If the variation described by a AAChange object has a known Bio::Variation::RNAAChange object, create the link with method AAChange().

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

RNAChange

Title   : RNAChange
Usage   : $mutobj = $self->RNAChange;
        : $mutobj = $self->RNAChange($objref);
Function: Returns or sets the link-reference to a mutation/change object.
          If there is no link, it will return undef
Returns : an obj_ref or undef

label

Title   : label
Usage   : $obj->label();
Function: 

           Sets and returns mutation event label(s).  If value is not
           set, or no argument is given returns false.  Each
           instantiable subclass of L<Bio::Variation::VariantI> needs
           to implement this method. Valid values are listed in
           'Mutation event controlled vocabulary' in
           http://www.ebi.ac.uk/mutations/recommendations/mutevent.html.

Example : 
Returns : string
Args    : string

trivname

Title   : trivname
Usage   : $self->trivname
Function: 

          Given a Bio::Variation::AAChange object with linked
          Bio::Variation::RNAChange and Bio::Variation::DNAMutation
          objects, this subroutine creates a string corresponding to
          the 'trivial name' of the mutation. Trivial name is
          specified in Antonorakis & MDI Nomenclature Working Group:
          Human Mutation 11:1-3, 1998.
          http://www.interscience.wiley.com/jpages/1059-7794/nomenclature.html

Returns : string
